Alstroemeria plant named Stamond

ABSTRACT

A new and distinct Alstroemeria variety producing flowers of good quality having inner petals with greyed purple spots against a primarily white background with a central section with yellow intonation.

BACKGROUND OF THE INVENTION

The present inventon relates to a new and distinct cultivar of Alstroemeria originated as a seedling by crossing as seed parent an unreleased seedling identified as 87r1345-1 and as pollen parent an unreleased seedling identified as 87G1069-2 among my collection of Alstroemeria seedlings maintained under controlled conditions in a greenhouse at Van Staaveren B.V., Aalsmeer, The Netherlands for developmental purposes. The varietal denomination of the new variety is `Stamond`.

The first act of asexual reproduction of `Stamond` was in Aalsmeer, The Netherlands by propagation by dividing rootstocks. Asexual reproduction through successive generations has demonstrated that the combination of characteristics as herein disclosed for `Stamond` are firmly fixed and retained through successive generations of asexual reproduction.

`Stamond` has not been observed under all possible environmental conditions. Phenotypic expression may vary with variations in environment such as temperature, light intensity, day length and growing and cultural conditions.

SUMMARY OF THE INVENTION

Flowers of the new variety of Alstroemeria, `Stamond`, are of the butterfly type and are characterized by inner lateral petals having greyed purple spots against a primarily white background with a central section having yellow intonation, and some greenish veination at the apices of outer petals.

The plant produces numerous flowering stems, which is a desirable characteristic in a cut-flower variety. The flower-bearing stems are long, strong and of excellent quality. It has been established that `Stamond` grows productively under greenhouse conditions. The variety is reproducible both by division of rhizomes and by tissue culture.
